Cellulose Acetate Membrane Filters, 0.45um, 25mm, Nonsterile, 100/Pk
GVS SKU: 1215635

Featuring a supported, hydrophilic cellulose acetate medium internally reinforced by an inert polyester web, these 25mm membrane filter discs deliver a 0.45um pore size in a nonsterile, 100 per pack format. The pure cellulose acetate membrane is naturally low binding, making it ideal for filtration applications where maximal recovery of protein is critical. The polyester web gives each disc exceptional strength to prevent cracking, tearing, breaking, and distortion when handled or creased.

Key Cellulose Acetate Membrane Characteristics

• Naturally hydrophilic: wets out readily for aqueous filtration without surfactant treatment.
• Low protein binding: pure cellulose acetate minimizes adsorption for maximum protein and analyte recovery.
• Supported structure: an internal inert polyester web provides dimensional stability and resists cracking, tearing, and distortion.
• High throughput: low binding characteristics support higher throughputs and reduce the number of filter changes when processing proteinaceous solutions.
• Sterilizable medium: dimensionally stable construction withstands autoclaving or steam sterilizing up to 135 degrees C (274 degrees F).

Key Construction Characteristics

• Format: 25mm flat membrane filter disc.
• Pore size: 0.45um for clarification and particulate removal.
• Sterility: supplied nonsterile.
• Pack: 100 discs per pack.

This membrane provides reliable, repeatable clarification while protecting sample integrity through low binding and high recovery. The reinforced structure maintains consistent performance under handling and on automated equipment, helping ensure dependable results across protein and aqueous solution filtration workflows.
